Background: Transgender women are individuals born male but identify as female. Many transgender women undergo gender-affirming hormone therapy to alleviate the distress that can occur due to gender incongruence. For transgender women, gender-affirming hormone therapy includes 17β-estradiol (E2) combined with an antiandrogen therapy (AA) or surgical intervention.

Eight loci were associated (p < 1 × 10) with TBRD in AI bred heifers and four loci were associated with TBRD in ET recipients.

Here, we assemble complete and gapless telomere to telomere (T2T) Y chromosomes for these species. We find that the pseudo-autosomal regions are similar in length, but the total chromosome size is substantially different, with the cattle Y more than twice the length of the sheep Y.
